tachment for plows, whereby the soil and the-clods thereof may be brokenand worked more satisfactorily than heretofore. T0 attain this feature,the attachment is provided with a'knife roller','--whichih'located'-inad- 'vance of the plow;and located of the knife roller isva plurality ofdisks or col'ters, which are designed to chop the soil and the clodsthereof in a lane par allel with the line of travel of the p low. Theknife roller chops the soil and clods thereof atright angles tothetravel of the plow; thus it will be noted that are soil is thoroughlybroken and worked by--the knife roller and the disks or colters, andafter being broken and thorou -hly worked, the plow in therear turns therrow. I

In the drawingsja certain form of device is disclosed, but inexperimentin'g and reducing topractice this form of device, if. theapplicant finds it necessary toalter various parts thereof, forinstance, the details of the structure, he is entitled to do so,provided the alterations fall within the scope of the appended claim.

Further features and combination ofparts will be hereinafter set forthand referred, to in the appended. claim. x

In the drawings Figure 1 is a plan view of a plow illustrating theattachment applied thereto. Fig. 2 is a side elevation of the (plow,also showing the attachment a plie Fig. 3 is a detail view of theattacment removed from the plow. Fi ,4 is a transverse sectional view throughc roller 10,.on line 4-4 of Fig. 2 in o'rder toillustrtte theconstruction and connection of the knife vblades 12. Fig 5 is a sideelevation-of the plow, showing the attachment. Fig; 6

- a plan View of the attachment detached from theplow showing parts inelevation and in section.

Referring to the, drawings, 1 denotes the plow beam, and 2' represents.the plow proper, while 3 designates the handles of the plow. The forwardextremity of the plow beam is'provided with the usual draft equalizer 4,whereby the plow may be drawn through the field.

Pro ecting downwardly from the beam 1, asat 5 and 6, are two projectionsor. beams 7 and 8. Journaled in a bearing of the projection or beam 7 isone end of the spindle 9 (with which the roller 10 rotates), while theother end of the said spindle 9 is journaled in a bearing of-anangularly disposed 11, which connects approximate y at .the'forwardportion of the plow beam 1. The roller 10 is rovided with :a' series ofelongated knife lades;'-12,'* which extend slightly tangentially of theroller, for instance in cross section.

Journaled bearings of the projection or beam-.8, and theangularlyfdisposed beam 11 a shaft 14;, which is provided with aplurality of disks or ooltels 15, designed to-rotate with the sald'shaft- On one end 40f the spindle of the'roller a beveled gear .16 isfixed, which mmhes with the. beveled ear17'of the shaft 18, on which aseriesof "disks or colters 19 are fixed. This shaft 18 is geared withthe shaffi 14 'by means of the beveled gears 20 ,and 2l. Thus it will.-be' observed that asthe knife roller is re- .volved by means of thetraction wheels 22;

(wnlzichgired caxrigg by the spifidle" of ro r'a .esi toengsigetegrounthe various unison. By-thel vision "of a jdevice' of this-design it willbe observed that the soil and theiclods .thereofwillibe easily workedand broken, sufliaiently to be turned by the plow in the rear. It willbeevident that the soil and't'he clods thereof will be ap proximatelypulverized.

The invention described, what is claimed asnew and usefufis-:

In a pier a plow beams and. anangularly ar a plm'ality of antin disksand a knife.

gztachmgnt, the cglmbiiiatiom of am avmg' ownwar rojecting raugti beam,of

or. colters. are. rotated in roller, shafts for the disks and the rollermounted in bearings of the downwardly projecting beams and the angularlydisposed beam, said knife'roller and disks being in advance of the plow,means for gearing the shafts to rotate in unison, means for causing theshafts to rotate, the knives of the roller being designed to out andbreak the soil and the elods, said knives being disevaaexz posed atright angles to said plow beam, and 10 at an ao ute angle to the axle ofthe disks.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.
